SPBING-TOGGLE.

To all whom mag cor wem:

Be it known that we DANIEL R. SHER- woon, a citizen of the U nited States, residing at Plainfield, in the county of Union and State of New Jersey, and Join: KARITZKY, a citizen of the United States, 'residin at Garwood in the county of Union and tate of New .lersey, have invented certain new and useful Improvements in Spring-Tog gles, of which the following is a specification, taken in connection with the accoman in drawin P. Oiir invention relates to toggles. More articularly it relates to means which will insure that the toggle head will rock or swing at an angle to the arm or bolt, after it has been inserted intothe wall or other support.

Our invention further relates to a toggle having a head provided with pivoting means midway its length, so that one end oes not overbalance the other, and means to insure the rocking of the toggle head when it has been inserted in the wall.

Our invention further relates to a rigid toggle head which is swung upon the pivoting nut by sprin means carried by the nut. Our invention a so covers the spring, as a separate article of manufacture, which may be sold separately and be applied to the toggle by the user.

Our invention further relates to certain combinations and details of construction which will be more fully hereinafter described in the specification and pointed out in the claims.

In the accompanying drawin reference numerals refer to simi ar the different figures.

Fig. 4 is a perspective view of the preferred form of spring which we employ;

Fig. 5 1s a perspective view, partly broken away, showing our invention a plied to a coil spring provided with only one arm 1n-v :tead of two as in thepreferred construcion.

In the toggle bolts now on the market it is customary to pivot the arm or bolt to the head so t at one end of the head is heavier than the other. That is, the pivot is not located substantiall ends of the head. F that end will be heavier than the other end, and consequently will have a tendency to overbalance it and cause thetoggle head, as soon as it is pushed home, to assume an angle to the arm or bolt to which it is pivoted. Avery slight obstruction inside the wall or support however will prevent gravity turning the head at ri ht angles to the hole, so that the work can e secured to the wall. Such toggle heads also have been found objectionable in practice in that a comparatively long head has to be used to obtain the overbalancing feature.

By our invention we positively insure that the toggle head will assume a osition at an angle to the hole, through which it has been inserted, even though it should scrape upon some slight obstruction which would be suflicient to prevent the 'ordinar form of gravity toggle from oppratin urther we can make our toggle ead 0 minimum length which will not only' save'metal, and therefore cost of manufacture, but it will permit our to gle to be used in thin partitions, or simi ar walls or structures, where the free space in which the to gle has to turn or swin is too limited for t e ordinary gravity togg e which has to be of'unnecessary length to, obtain the overbalancing feature.

In our invention the toggle head is rigid and referably formed of onepiece of sheet meta, which gives the maximum strength in spanning the opening in the wall.

midway between the y having one end longer,

In the illustrative embodiment of our invention as shown in the drawin s, 1 is a toggle head having a base 2, and anges 8, 3 one of the flanges being omitted in Fig. 1. In the preferred construction we mount a nut 6 having trunnions 7, 7, midway between the en s 4 and 5 of the toggle head 1. These trunnions 7, 7 are received in openings or bearings 8, 8, punched 'or otherwise formed in the flanges 3, 3.

In our invention we employ spring means carried by the nut 6 to cause the toggle head 1 to swing at right angles to the bolt 9. Various forms of s ring means carried by the nut may be emp oyed. We have shown as one embodiment of our invention a spring 10, Fig. 4, formed of wire, or other suitable material, bent back upon itself to form a coil 11 to receive the bolt 9, the two ends 12, 12 are then bent down from the coil substantially parallel to each other and then bent at the points 13, 13, 14, 14, 15, 15 and 16, 16 so as to form, in effect, an open cage 17 within which the nut 6 is yieldingly held. The arms 12, 12 are then brought parallel to each other as shown in Fig. 4 and 1. The nut 6 is inserted within the pocket 17 by simple manipulation where it is yieldingly held; the nut 6 and spring 10 move together, In using our invention the bolt 9 may be passed through the work 18, or other suitable article to be supported on the wall or other suitable support 19, the end of the bolt being passed through the coil 11 into engagement with the threads of the nut 6. By bending down the end 5 of the toggle head so that it will come into alinement with the bolt 9, the toggle head 1 can be inserted within the hole 20 in the support or wall.19. This places considerable tension upon the spring 10, the free arms 12, 12 of the spring bearing upon the inside of the toggle head 1. As soon as the end 5 escapes the inner surface 21 of the wall or other suitable support 19, the spring 10 will throw the toggle head 1 sharpl at right angles to the bolt 9 as shown in ig. 3. The work 18 is then securely held to the face 22 of the wall by simpl screwing up the bolt 9.

While we pre erably use two free arms 12, 12 of the spring 10 to bear upon the inner surface of the toggle head we may use simply one such arm as shown for exam la in Fig. 6.

ur invention may also be employed with toggle bolts in which the toggle head 23, Fig. 5 has one end 24 longer than the end 25 so that gravity will have a tendency to rock the head 23 with relation to the bolt 9. In this form our spring, carried-by the nut 6, serves to accentuate and make sure the action of gravity by causing the arm 12, 12 to kick over the end 25 of the toggle bolt,

'when it escapes the inner surface 21 of the wall or other suitable sup ort 19.

Having thus described t is invention in connection with illustrative embodiments thereof, to the details of which we do not desire to be limited, what is claimed as new and what is desired to secure by Letters Patent is set forth in the appended claims.

What we claim is 1. In a toggle, the combination of a one piece head, a bolt, a nut, and -a spring carried by the bolt and embracing the nut and adapted to rock the one p1ece head with relation to the bolt.

2. In a toggle, the combination of a one p1ece head, a bolt, a nut, and a spring carried by the bolt and embracing the nut and havlng one or more free arms and adapted to rock the one piece head with relation to the bolt.

3. In a toggle, the combination of a one p1ece head, a nut, and a spring embracing the nut.

4. In a to gle the combination of a one p1ece head, aving bearings for a nut, a nut mounted on said bearings and a spring yieldingly embracin the nut, adapted to move with it and a apted to rock the one piece head.

5. In a toggle the combination of a one p1ece head, having bearings for a nut, a nut mounted on said bearings and a spring yieldingly embracing the nut, adapted to move with it and adapted to rockthe one piece head, said spring having a portion adapted to receive a bolt.

6. In a toggle the combination of a one piece head having bearings for a nut, a

article of manufacture for a toggle comprising a spring having a central portlon to receive a bolt, a cage to surround a nut, and one or more free arms.

8. An article of manufacture comprising a toggle head, a bent wire spring having a coil portion to receive the bolt, a bent portion to substantially surround and embrace a nut, and one or more free arms.
